WINDOW FRAME AND SASH.

SPECIFICATION forming part of Letters Patent No. 785,370, dated March21, 1905.

Application filed March 10, 1902. Serial No. 97,436.

To (1 17. ufl'l/n'm/ it may concern:

Be it known that I, LEONARD M. NEABREY, a citizen of the United Statesof America, and a resident of Oincinnati,in thecountyof Hamilton andState of Ohio, have invented certain new and useful Improvements inWindow Frames and Sashes, of which the following is a specification.

The object of my invention is a window the frameof which is devoid ofparting-strips and beadings for the sashes, in which the sashes mayeasily be placed in and removed from the frame, and which isantirattling, proof against the weather and fire and which automaticallyadjusts itself to shrinking or swelling in the parts, so that the sashat all times both fits the frame snugly and slides freely therein.

Referring to the accompanying drawings,

in which my invention is illustrated as applied to a metallic frame andsash, Figure 1 is a sectional perspective view of a Window embodying myinvention Fig. 2 is a view, partly in front elevation and partly incross-section, upon line y Fig.3, which is a cross-section on line's 2,Fig. 1. Fig. 4 is a detail perspective view of my expansible metallictube for retaining the sashes movably in their frames.

Referring to the parts, both sides a of win dow-frame A are plain exceptfor two vertical semi-elliptic grooves a a which extend from top tobottom of each side of the frame. Both the upper and lower sashes B andB have similar grooves b and Z) upon each side, running the full lengthof the sash, except for a flange 5*, which is left at the lower ends ofeach of the grooves. The sashes are placed in the frame so that groovesb in the upper sash register with grooves a and grooves 72 in the lowersash register with grooves 00?. Then elliptical retainers consisting ofmetallic tubes O are placed in the elliptical ways formed by the groovesb and a and by grooves b and a Tubes O rest at their lower ends uponflanges Z) of the sashes, slide with the sashes, and are made of alength slightly less than that of the height of the sashes, so that theymay be readily inserted and removed from their ways, an operation whichis performed when the sashes are at the lowermost limit of their travel.Each of tubes O is made, preferably, of resilient metal rolled into atube with the edges free and overlapping one another and which when notinserted in the ways is of a greater circumference than they, so thatwhen placed in position it fits the ways snugly and expands to take upany shrinkage in the frame and sashes, and should the ways becomecontracted from any cause the tube likewise assumes a smaller diameterby becoming more tightly rolled, so as not to bind the sash in itsvertical movements.

It is seen that by my construction I do away with the beading andparting-strips of the frame, the sashes being held in place by andsliding with the metallic tubes; that to remove the sashes from theframe or insert them therein it is necessary only to bring the sashes tothe lower limit of their travel and lift the tubes out of their ways,when the sashes may be lifted out of the frame, and that the tubesfitting their ways snugly they hold the sashes against rattling andprevent the passage of grooves and removable elliptical retainers to fitinto the elliptical ways formed by the grooves in the frames and in thesashes to retain the sashes and t6 permit of their sliding in the framesubstantially as shown and described.

2. A window-frame having vertical semielliptical grooves in its sides,in combination with sashes having similar grooves to register with saidgrooves, and firm removable tubes to fit into the elliptical ways formedby the grooves in the frame and in the sashes to retain the sashes andto permit their sliding in the frame substantially as shown anddescribed.

3. A window-framehaving vertical grooves in its sides in combinationwith sasheshaving 'grooves similar to and registering with the groovesin the frame, flanges at the lower ends of the grooves in the sashes andretainers of a length less than the height of the sashes and of theshape and circumference of the ways formed by the grooves in the sasheswith those in the frames and resting upon the flanges LEONARD M. NEABBEY.
